1 Claim.

The object of the present invention is to provide a pin wheel device,which, in its actuation, will produce a sound simulating that of anairplane in flight. In other words, the sound produced may be similar tothe action of the propelling blades of an aircraft engine in the airwhen the aircraft is in flight.

The specific object of the invention is to provide such a device whichwill be very simple in construction and at the same time of attractiveform.

The invention will be described with reference to the accompanyingdrawing, in which:

Figure 1 is a view in elevation showing an embodiment of the invention;and

Figure 2 is a transverse section on the line 2-2 of Figure 1.

In the construction of my sound producing pin wheel, I utilize twohemispheres, preferably of light plastic, which plastic may be opaque incolor or may be transparent, as desired. A characteristic of myinvention is that the center area of the pin wheel proper is utilized asboth a connecting and separating member for the two hemispheres. Also,one of the hemispheres immediately carries one or more vibratory soundproducing blades which co-act with a fixed ratchet carried by a shaftwhich in turn is provided with a handle.

Referring to the drawings, it will be seen that the primary pin wheelmember is formed from a sheet of plastic or other suitable material,having a central annular member I and projecting blades 2. This centralannular member may, if desired, be cut out at its center. This isunnecessary, however, and I prefer that the center be of disk-like form,and that its diameter be slightly greater than the diameter of thehemispheres.

The hemisphere 3 has its peripheral margin abutted with member I andcemented thereto. Hemisphere 3, in the present embodiment, carries tworelatively stiff blades or vibratory members 4, and these members may becemented or otherwise secured to the interior wall of said hemisphere 3.These blades or vibratory members are actuated by a ratchet wheel 4x orother suitable form of striker adapted to flex and release the vibratorymembers 4 a plurality of times in each rotation of the pin wheel proper.The ratchet wheel 43: is fixed to a shaft 5, which shaft in turn isextended as an axial member of a handle 6.

Secured to the side of member I opposite that of hemisphere 3 is asecond hemisphere l, and shaft 5 runs through both hemispheres and isheaded at 5x outside of hemisphere l.

The blades 2 of the pin wheel proper are so formed that when struck witha forward blast of air, or when the device is rapidly moved throughmotionless air, the blades with their spherical carriers composed ofhemispheres 3 and 7 will rotate in the direction of the arrow, Figure 2.As the vibratory members it are drawn over the ratchet wheel 4x, thedesired sound will be produced.

It will be understood that the teeth or projections of the ratchet wheelwhich are engaged by the stiff, but vibratory blades 5, may be of anydesirable form, that the blades 4 may be constructed of any suitablematerial, and that various changes may be made in the form andarrangement of the elements without departing from the spirit of theinvention.

What I claim and desire to secure by Letters Patent being as follows:

A sound producing pin wheel comprising a blade member formed of a sheetof material having a central disk-like area and a plurality of bladesextending radially therefrom, said blades being of substantially equalarea to provide a balanced assembly two hemi-spherieal members, eachmember having its' periphery secured to one side of said annular centralmember of the pin wheel, a shaft extending through the sphere formed bythe two hemi-spherical members and the intermediate disk-like area ofthe pin wheel, a ratchet on said shaft and a vibratory blade membercarried interiorly of one of said hemispheres and engaging the peripheryof the ratchet.
